It's always a tradeoff. Big issue I see with your sail is the foot length and clearance with the forward lower. Sheeting that kind of sail is always a tricky one to get right without the sheet or clew chafing on something.
If it was me I would be tempted to go with a solent stay led to a point just behind the roller. This is a pretty useful thing to have for running wing and wing, light sails
, and with some sort of 100% jib
for heavy windward work, as well as being able to be used with a storm jib
I don't like the orange option much, even though it seems to work it really needs runners, and I can't say I like the way that panel of mast has poor lateral support. If the section is a big chunky one it seems to work fine, but I would rather not worry about it in storm jib weather
Ideally for just the storm jib, I would use the spreader mount, or pretty close to it maybe 6% of the panel length above them max. Then I would look at having the luff of the storm jib trimmed to reduce the foot length so that it cleared the forward lower shroud
completely. Or the stay could be attached further forward on deck
to give the sail clearance.
This is the configuration I used on Snow Petrel1, together with some spectra runners for insurance
, and a tight luff.
Just beware that with a heavily reefed main and a storm jib set up like this the loads on the lowers are pretty high, much higher than they would normally be loaded with a genoa
, when the caps take much of the strain. On some rigs A solent stay is probably a much safer bet, distributing the load in a better way.
It's a very small sail, but it really provided a lot of extra drive, and wasn't in the way at all, the genoa could tack around it easily enough. Very useful offshore
, but inshore I removed all the gear
and used the solent stay instead. Offshore
I had two storm jibs. One for the solent and one for the babystay. Never had to use them both, but it would have made a very snug rig.
Waiting for wind
at 60 degrees south. Shows the proportions well. Ideally I would have raised the Babystay about 500mm (1.5 feet) or so up the mast, and got a bigger storm jib. I would have used a wishbone boom to keep it flat and make it self tacking. But i've sold her now... New Project!
The Solent stay running with my light drifter to leeward, sheeted off the main boom. this was a very good downwind rig. Fast, stable and easily handled as the wind
increased. So good in light stuff I didn't need to pull out the spinnaker
once at sea.
The biggest issue with running a storm jib of the solent stay is that it can't be used at the same time as the genoa, and it's more prone to luff sag, and wobbling. Balance may be better, or worse, depending on the boat. certainly for downwind it's better on a solent stay, further forward. Upwind it depends. probably better further aft, but I've gone to windward with just a storm jib on the outer forestay, no main. and it worked as long as the wind was strong enough to keep the lee rail under! I wouldn't have been able to tack though, or at least I didn't bother to try...
